There is good news from the world of science, according to scientists in Israel on Monday has unveiled the world's first 3D-printed heart with human tissue and blood vessels.
This writes the French news agency AFP.
Although there is still a long way to go, so the researchers hope that one day they will be able to produce hearts, which could be used for transplants in humans.

the Heart has been produced by researchers from the university of Tel Aviv and is the size of a kaninhjerte.
- this is The first time ever that anyone has been able to construct and print out a complete heart with cells, blood vessels, ventricles and chambers, says the Number Dabir, who is the responsible behind the project, according to AFP.
in The past managed to print out a heart, but not with the same level of detail as it is managed for the israeli scientists.
even Though there is great rejoicing, there are still many challenges before a 3D printed heart is ready to be transplanted into a human. Now the researchers must try to learn the heart, how it 'behaves' like a genuine heart. The cells are able to pull themselves together, but they still can not pump the blood around.

- There might be body printers of the largest hospitals in the world for 10 years, where you will transplant 3D printed hearts routinely, explains the Divir.
In the development of the heart took the researchers adipose tissue from patients and used it as 'ink' to print the heart. By using tissues from patients eliminates the possibility that the body after a transplant will reject the heart.
the Challenges for the future is to find out how to get the cells to expand and ensure enough tissue to recreate a human heart. In addition, the current 3D printers are also limited by their size.
